Functions:

As an antioxidant, vitamin E acts as a peroxyl radical scavenger, preventing the propagation of free radicals in tissues, by reacting with them to form a tocopheryl radical, which will then be reduced by a hydrogen donor (such as vitamin C) and thus return to its reduced state.
As an enzymatic activity regulator, for instance, protein kinase C (PKC), which plays a role in smooth muscle growth, can be inhibited by α-tocopherol.
Vitamin E also has an effect on gene expression. Macrophages rich in cholesterol are found in the atherogenetic tissue.
Vitamin E also plays a role in neurological functions,and inhibition of platelet aggregation.
Vitamin E also protects lipids and prevents the oxidation of polyunsaturated fatty acids.
